Purpose : This study is to examine the painful dysesthesia of lip & gingiva followed
after implant surgeries and to evaluate the prognosis of microsurgical epineurotomy &
tubulization with e-PTFE tubes.
Method : Three patients who had been suffered from painful anesthesia and
dysesthesia following dental implant surgeries were examined periodically and followed
for over 1 year after epineurotomy and e-PTFE tubulization. Neurosensory dysfunctions
were examined by Static Light Touch Threshold, Moving Direction Discrimination. Two
Point Discrimination, Pin-Prick Nociception. Visual Analog Scales and Tinel sign. The
subjective symptoms were confirmed by SSEP and DITI prior to surgical exploration.
Result : Two patients complained of continuous tearing and lancinating pain disclosed
complete avulsion of IAN and degenerative changes with neuroma. One patient
complained of mild painful dysesthesia revealed partial adhesion & fibrous epineural
changes. Two patients whose IAN were explored after over 1 year resulted in only mild
improvement in sensory recovery and moderate reduction of pain score. While the
patient to whom decompression & epineural repair were given in 3 months after nerve
injuries resulted in satisfactory improvement in sensory function and pain reduction.
Conclusion : Painful dysesthesias occurred after implant placement were resulted from
neurotmesis and disclosed degenerative neuropathy. Therefore, the micro-surgical
explorations and repairs (epineurotomy, decompression neurolysis, and neurorrhaphy) can
be recommended for known injuries as early as possible. For the delayed painful
dysesthesia lasted over year, however, epineurotomy & tubulization could be an option
to improve the painful discomfort but not satisfactory.
